LaMotte's Research and Development team spent 7 years pioneering this new technology. All you do is add pool or spa water to the disk to measure all of the tests in just 60 seconds. It's the most advanced system for precise use of wet chemistry methods ever produced. Now in-store pool and spa analysts can achieve greater precision than current water labs without time consuming procedures or sacrificing accuracy by using test strip scanners.
